In the busiest border city of Tijuana, thousands of people come here everyday, looking for a chance to cross the U.S.-Mexico border one day. Some of them have family on the other side. Some believe they can improve their life once they get there. Some have been rejected several times. Some live in informal settlements with no flood control infrastructure.

The nature of border is just a line defined by politicians. Seawater flows through the border wall. Birds fly over as if the line doesn’t exist.  Should the border define how people live? Or is it another way around?
